Westinghouse 12500 Watt Dual Fuel Portable Generator
The Westinghouse 12500 Watt Dual Fuel generator runs on gasoline or propane and includes a remote start for quick power restoration. It supports a transfer switch-ready setup and provides multiple outlets with safety covers, making it suitable for mid to large homes that need substantial backup power. Key features include 9500 running watts on gas and 8500 running watts on propane, a 6.6-gallon fuel tank with a fuel gauge, and an engine with automatic low oil shutdown. This option is best for homeowners who value remote-start convenience and robust peak power for essential circuits plus some high-demand loads. A potential limitation is longer runtime on propane, depending on load and tank size.
Westinghouse 14500 Peak Watt Dual Fuel Generator
This model is designed for larger homes or remote sites requiring substantial initial power. It offers up to 14,500 peak watts and 11,500 running watts on gasoline, with propane at 13,500 peak and 10,500 running watts. It can run for up to 19 hours on a 9.5-gallon tank and provides similar safety features to the smaller Westinghouse unit, including a CO shutdown option and multiple outlets with covered safety. It is best for customers who need extended runtime and higher peak power for simultaneous air conditioning, heating, and appliances. A caution is that the unit is heavier and less portable than smaller options.
Westinghouse 13500 Peak Watt Dual Fuel Generator
With 13,500 peak watts and 9,500–10,500 running watts depending on fuel, this Westinghouse model blends strong peak power with versatile mid-range running power. It features a remote electric start, transfer-switch readiness, and a CO shutdown. The engine is a robust 500cc design with a digital hour meter for maintenance awareness. This option suits households that want a balanced solution—capable of handling common appliances plus air conditioning during outages. The main limitation is similar to other larger units: higher weight and reduced maneuverability compared to smaller portable units.
DuroMax XP13000EH 13,000-Watt Dual Fuel
The DuroMax XP13000EH emphasizes dual-fuel flexibility with substantial power for whole-home back-up needs. It includes an electric start and is marketed as a whole-home ready option with transfer switch compatibility. The engine is designed for durability, with a focus on power reliability in storms or outages. Best for households that require high power and longer run times, particularly when gasoline is available. A notable limitation is that the unit’s heavier weight may require careful handling and setup during installation.
Westinghouse 6500 Watt Dual Fuel Generator
Geared toward mid-sized homes, this 6500-watt dual-fuel option provides solid performance with a 4.7-gallon tank and a fuel gauge. It features multiple outlets, including a 30A RV receptacle and transfer-switch readiness. Best for homeowners who need reliable backup for essential loads like refrigeration, lighting, and communications without moving into the larger, heavier units. A limitation is the moderate running watts when under heavy load, which may require prioritizing circuits during long outages.
WEN 5,600-Watt Dual Fuel with CO Watchdog
The WEN DF5600X provides a strong dual-fuel platform with 5,600 surge watts and 4,500 running watts on gasoline, plus 5,000 surge and 4,050 running watts on propane. It includes a wheel kit and electric start, plus CO watchdog safety to automatically shut down on carbon monoxide detection. Best for budget-conscious buyers who still need reliable power for essential circuits and moderate loads. A caution is that it has lower overall capacity for whole-home backup compared with the largest Westinghouse or DuroMax models.
Buying Guide: Key Considerations For Choosing A Dual Fuel Generator
- Power needs: Determine essential circuits and peak loads. Bigger homes may require 10,000+ running watts; smaller needs can be met with 4,000–8,000 running watts.
- Fuel flexibility: Dual fuel models offer gasoline for short bursts and propane for longer run times or cleaner emissions. Consider fuel availability in your area.
- Startup and runtime: Remote electric start saves effort during outages. Look for models with long run times on full tanks and clear fuel gauges.
- Transfer switch compatibility: If you plan to connect to a home transfer switch, ensure the generator is transfer-switch ready and matches your panel rating (30A or 50A receptacles, etc.).
- Safety features: CO shutoff, rubber outlet covers, and automatic low-oil shutdown reduce risk during operation.
- Portability vs. power: Heavier units deliver more wattage but are less portable. Decide whether you need wheeled portability or stationary backup power.
- Outlets and versatility: Look for multiple 120V outlets, 240V options, and RV-ready receptacles to cover various setups.
- Maintenance and lifespan: Choose models with durable engines and practical maintenance features like hour meters and accessible oil changes.
Frequently Asked Questions
- What is dual fuel power? Dual fuel generators run on two fuel types, typically gasoline and propane, offering flexibility during outages or fuel shortages.
- Do I need a transfer switch for home backup? For whole-home backup, a transfer switch is recommended to safely isolate the generator from the grid and avoid backfeeding.
- How many watts do I need for basic home backup? Essential loads typically require 3,000–6,000 running watts for a small-to-mid home, while larger homes may need 8,000–12,000+ running watts.
- Is propane better than gasoline for prolonged outages? Propane tends to store longer and burn cleaner, but efficiency and runtime depend on load and tank size. Gasoline offers higher power but shorter storage life.
- What safety features should I look for? CO sensors/shutdown, automatic low-oil shutdown, grounded outlets, and fuel gauge indicators enhance safe operation during outages.
- Can these generators power an entire home? Large dual fuel models can support many critical circuits, but “whole-home” power requires careful load assessment and a properly sized transfer switch or interlock kit.
